Hello! My name is Zalgo and I am here to help you out on this amazing day. The way that the younger plant looks the same as the parent plant is because of "Asexual Reproduction". Asexual Reproduction is how plants can reproduce. Considering it is a plant and not a human asexual means that plants reproduce without the need of "sexual intercourse".
I hope that this helps! :P
